 HISTORY of the 7-Zip
 --------------------
 
+20.00 alpha    2020-02-06
+-------------------------
+- 7-Zip now supports new optional match finders for LZMA/LZMA2 compression: bt5 and hc5, 
+  that can work faster than bt4 and hc4 match finders for the data with big redundancy.
+- The compression ratio was improved for Fast and Fastest compression levels with the 
+  following default settings:
+   - Fastest level (-mx1) : hc5 match finder with 256 KB dictionary.
+   - Fast    level (-mx3) : hc5 match finder with 4 MB dictionary.
+- Minor speed optimizations in multithreaded LZMA/LZMA2 compression for Normal/Maximum/Ultra 
+  compression levels.
+- bzip2 decoding code was updated to support bzip2 archives, created by lbzip2 program.
+- Some bugs were fixed.
+- New localization: Turkmen.
+
+
+19.02 alpha    2019-09-05
+-------------------------
+- 7-Zip now can unpack files encoded with Base64 encoding (b64 filename extension).
+- 7-Zip now can use new x86/x64 hardware instructions for SHA-1 and SHA-256, supported
+  by AMD Ryzen and latest Intel CPUs: Ice Lake and Goldmont.
+  It increases
+    - the speed of SHA-1/SHA-256 hash value calculation, 
+    - the speed of encryption/decryption in zip AES, 
+    - the speed of key derivation for encryption/decryption in 7z/zip/rar archives.
+- The speed of zip AES encryption and 7z/zip/rar AES decryption was increased with 
+  the following improvements:
+   - 7-Zip now can use new x86/x64 VAES (AVX Vector AES) instructions, supported by 
+     Intel Ice Lake CPU. 
+   - The existing code of x86/x64 AES-NI was improved also.
+- There is 2% speed optimization in 7-Zip benchmark's decompression.
+- Some bugs were fixed.
+
+ 
+19.00          2019-02-21
+-------------------------
+- Encryption strength for 7z archives was increased:
+  the size of random initialization vector was increased from 64-bit to 128-bit,
+  and the pseudo-random number generator was improved.
+- Some bugs were fixed.
+
+
+18.06          2018-12-30
+-------------------------
+- The speed for LZMA/LZMA2 compressing was increased by 3-10%,
+  and there are minor changes in compression ratio.
+- Some bugs were fixed.
+- The bug in 7-Zip 18.02-18.05 was fixed: there was memory leak in xz decoder.
+- 7-Zip 18.02-18.05 used only one CPU thread for bz2 archive creation.
+  
+
+18.05          2018-04-30
+-------------------------
+- The speed for LZMA/LZMA2 compressing was increased 
+    by 8% for fastest/fast compression levels and 
+    by 3% for normal/maximum compression levels.
+- 7-Zip now shows Properties (Info) window and CRC/SHA results window
+  as "list view" window instead of "message box" window.
+- Some improvements in zip, hfs and dmg code.
+- Previous versions of 7-Zip could work incorrectly in "Large memory pages" mode in
+  Windows 10 because of some BUG with "Large Pages" in Windows 10. 
+  Now 7-Zip doesn't use "Large Pages" on Windows 10 up to revision 1709 (16299).
+- The vulnerability in RAR unpacking code was fixed (CVE-2018-10115).
+- Some bugs were fixed.
+ 
+
+18.03 beta     2018-03-04
+-------------------------
+- The speed for single-thread LZMA/LZMA2 decoding
+  was increased by 30% in x64 version and by 3% in x86 version.
+- 7-Zip now can use multi-threading for 7z/LZMA2 decoding,
+  if there are multiple independent data chunks in LZMA2 stream.
+- 7-Zip now can use multi-threading for xz decoding,
+  if there are multiple blocks in xz stream.
+- New localization: Kabyle.
+- Some bugs were fixed.
+
+
 18.01          2018-01-28
 -------------------------
 - 7-Zip now can unpack DMG archives that use LZFSE compression method.
